I have been working with ebooks recently. I have no skills in programming language. I only use Office Word processor to edit , remove spaces, page breaks, insert images, make a linkable TOC and then convert to a “web page filtered” in order to convert in Calibre as a EPUB, MOBI or PDF.

I learn all of this stuff in the Smashwords formatting guide, because this is the store of my first publish ebook. This is the far as I get on ebooks.

My friend recently came up with an idea of place or add a watermark in all pages for a couple of ebooks. We are going to lend those ebooks to an entity. This watermark is important to have in all three formats that I have been working with; EPUB, MOBI and PDF. Make a PDF format is easy, and i already have it. But the other two...hmm not so easy for me. So here I am.

I tried to convert the file in Calibre with a watermak in it, like i used to do with my other ebooks, but in the conversion, Calibre remove the mark.
